USB WiFi learning exercise

balanga

I bought a noname USB WiFi dongle from a supermarket and am in a process of trying to get it working on my ThinkPad X61 laptop.

The adapter is branded Qilive, which I have never heard of. The packaging said 'Wireless USB adapter', WiFi B/G/N, 300Mbps. No details about chip.

To start with I inserted in the laptop and ran lsusb from sysutils/usbutils which revealed:-

Bus /dev/usb Device /dev/ugen0.4: ID 0bda:818b Realtek Semiconductor Corp. RTL8192EU 802.11b/g/n WLAN Adapter

Just to be sure I did a lookup of PrdID/VendID on https://the-sz.com/products/usbid/ which gave me:

0x0BDA 0x818B Realtek Semiconductor Corp. RTL8192EU 802.11b/g/n WLAN Adapter

same as lsusb, so am wondering if this is embedded in the device somewhere....

So, a search for freebsd wifi cards RTL8192EU led to Thread 88055, but I can't tell if that actually works with my adapter under 13.2-R.

My /etc/rc.conf
Code: 
wlans_rtwn0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"

When I insert the adapter ifconfig wlan0 shows
Code: 
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ether 90:de:80:1a:95:36

ifconfig wlan0 scan detects my wireless network

Can anyone shed any light on what is happening or what I may have missed?



[/CMD] produces
 
I have now installed 14.0-R and the previous error (has partially) disappeared.

ifconfig wlan0 shows:

What am I missing?

Is there a log of DHCP attempts with reason for no link?
 
How do I trace what happens when processing this line in /etc/rc.conf:?

ifconfig_wlan0="WPA SYNCDHCP"

if doesn't work as expected, is there any way to tie this down to a driver/hardware problem or a configuration problem?

If configuration, is that down to /etc/rc.conf and/or /etc/wpa-supplicant.conf?
 
Try static IP:

ifconfig wlan0 inet 192.168.x.x netmask 255.255.255.0
route add default 192.168.x.1
echo "nameserver your-dns-server" >> /etc/resolv.conf
ifconfig wlan0
ping any-url

Or run wpa_supplicant manually with the debug option, and check the dhclient service log.

Open in different terminals (interactive mode):

wpa_supplicant -d -i wlan0 -c /etc/wpa_supplicant.conf
service dhclient restart wlan0
tail -f /var/db/dhclient.leases.wlan0

rc.conf()
rc_debug (bool) If set to "YES", enable output of debug messages
from rc scripts. This variable can be helpful in diagnos-
ing mistakes when editing or integrating new scripts. Be-
ware that this produces copious output to the terminal and
syslog(3).

rc_info (bool) If set to "NO", disable informational messages from
the rc scripts. Informational messages are displayed when
a condition that is not serious enough to warrant a warning
or an error occurs.
